2014 991 Turbo S in Colorado USA

This 991 Turbo S was commissioned for a client in Colorado with a very specific vision – retain the comfort, refinement, and everyday usability, while elevating its performance into supercar territory.
Central to achieving that is the integration of the Vonnen Shadow Drive system, which transforms the character of the car without compromising its character. Unlike traditional modifications that can make a car feel temperamental or overly aggressive for daily use, Vonnen Shadow Drive works seamlessly within the drivetrain, adding a layer of instant, responsive electric torque that enhances the driving experience and provides torque fill to and also works to negate turbo lag.
By incorporating Vonnen Shadow Drive directly into the drivetrain, total system output is pushed beyond 700 horsepower. Paired with the Turbo S’s PDK transmission and all-wheel drive system, the added power from Vonnen Shadow Drive is translated into forward motion with remarkable efficiency and control. The result is a car that launches hard, accelerates relentlessly, and remains composed and usable in everyday driving.
